Abstract
The utility model discloses a kind of efficient water-ring vacuum pumps of single impeller, including chassis, motor and the single impeller pump housing are fixed with by bolt assembly on chassis, the single impeller pump body is prejudicially equipped with impeller, the motor is connected with the shaft of the single impeller pump housing by shaft coupling, is connected with air-breathing communicating pipe and moisture trap at the top of the pump housing.The utility model compared with prior art the advantages of be: the efficient water-ring vacuum pump of single impeller uses the structure type of single-stage single-acting, with simple, easy to maintenance, reliable for operation, the energy-efficient advantage of structure.Have that vacuum degree is high, the remarkable advantages such as low in energy consumption relative to widely used SK, 2SK, SZ series water-ring vacuum pump in the current country, is SK, 2SK, SZ series water-ring vacuum pump ideal substitute products.
Description
Technical field
The utility model relates to vacuum pump more particularly to a kind of efficient water-ring vacuum pumps of single impeller.
Background technique
Water-ring vacuum pump is the vacuum pump of extraction underground methane.The vacuum pump negative pressure of suction is high, flow is small, applicable
Mine that is little in pumping volume, requiring negative pressure of suction high uses.Water-ring vacuum pump safety is good, and general mine requires higher
Negative pressure of suction, so using wide.But current domestic widely used SK, 2SK, SZ series water-ring vacuum pump
Vacuum degree is not good enough, power consumption is high, and operational reliability is not good enough, and inconvenient maintenance.
Summary of the invention
The utility model is to provide a kind of efficient water-ring vacuum pump of single impeller to solve above-mentioned deficiency.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of single impeller High-efficient Water circular vacuum
It pumps, including chassis, motor and the single impeller pump housing is fixed with by bolt assembly on chassis, the single impeller pump body is prejudicially
Impeller is installed, the motor is connected with the shaft of the single impeller pump housing by shaft coupling, and air-breathing company is connected at the top of the pump housing
Siphunculus and moisture trap.
Further, shield is equipped at the shaft coupling, the shield is fixed on chassis.
Working principle of the utility model is: impeller is eccentrically mounted in the pump housing, when the impeller is rotated.Water is by centrifugal force
It acts on and forms a rotation water ring on pump housing inner wall, it is not tangent with wheel on water ring, it rotates in the direction of the arrow, in the mistake of preceding half way around
Cheng Zhong, water ring inner surface is gradually detached from wheel, therefore the space formed between impeller blade is gradually expanded, and space gas pressure reduces,
Gas is inhaled into space；During rear half way around, water ring inner surface is gradually close with wheel, and interlobate space is gradually reduced,
Air pressure power increases, and when being higher than exhaust port pressure, gas is discharged, and so far impeller often rotates a circle, and changes between blade once,
Many spaces ceaselessly work, and pump just continuously intake-gas.
The utility model compared with prior art the advantages of be: the efficient water-ring vacuum pump of single impeller use single-stage single-acting
Structure type, with simple, easy to maintenance, reliable for operation, the energy-efficient advantage of structure.Make extensively relative to the current country
SK, 2SK, SZ series water-ring vacuum pump remarkable advantages such as high, low in energy consumption with vacuum degree, are SK, 2SK, SZ Series of Water
Ring vacuum pumps ideal substitute products.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail below with reference to embodiment.
It is solid by bolt assembly 2 on chassis 1 as shown in Figure 1, a kind of efficient water-ring vacuum pump of single impeller, including chassis 1
Surely there are motor 3 and the single impeller pump housing 4, impeller, the motor 3 and single impeller are prejudicially installed inside the single impeller pump housing 4
The shaft of the pump housing 4 is connected by shaft coupling 5, is connected with air-breathing communicating pipe 6 and moisture trap 7 at the top of the pump housing 4.
Further, shield 8 is equipped at the shaft coupling 5, the shield 8 is fixed on chassis 1.
Working principle of the utility model is: impeller is eccentrically mounted in the pump housing, when the impeller is rotated.Water is by centrifugal force
It acts on and forms a rotation water ring on pump housing inner wall, it is not tangent with wheel on water ring, it rotates in the direction of the arrow, in the mistake of preceding half way around
Cheng Zhong, water ring inner surface is gradually detached from wheel, therefore the space formed between impeller blade is gradually expanded, and space gas pressure reduces,
Gas is inhaled into space；During rear half way around, water ring inner surface is gradually close with wheel, and interlobate space is gradually reduced,
Air pressure power increases, and when being higher than exhaust port pressure, gas is discharged, and so far impeller often rotates a circle, and changes between blade once,
Many spaces ceaselessly work, and pump just continuously intake-gas.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model specification and embodiment content, directly or indirectly use
In other related technical areas, it is also included in the patent protection scope of the utility model.
